nevermind a hippo tang anymore, this is the tang that i think i'd centerpiece a 180 or larger around. not just the looks are awesome but the name Achilles like the greek worrior but having a surgeon blade rather then a spear and sword :P

You did see the "expert only" tag they have on it didnt you? They are not hardy fish at all. Their definition of expert only is

Expert Only
Organisms in the "Expert Only" category are very difficult to maintain in captivity in the long term. The requirements of many of these corals and invertebrates are specialized, and may need to be kept in a species-specific aquarium. These species are best kept by the most advanced hobbyists and research institutions. A well-established reef aquarium is a must for these species.

thats why i said it would be the center piece if i did it, but everytime i find a decent 180 for sale they are either to far or they sell right away

they are hard to keep. not impossible, but hard. i actually like clown tangs a lot better than achilles. much more color, but need a big tank for them too..i would say 300 or better, only because the other fish will need a large tank to escape it's wrath.
